Hi Bruce, I haven't had this problem yet. I may be able to provide a bit of info though.
As you know, there are webs fiberglassed to the interior of the hull that provide reinforcement. These webs form a reinforcing grid that C&C referred to as the 'Spider'. These individual webs are generally shaped like an inverted 'U' and are hollow. I think, looking at the drawings I have (they don't show this detail very well), there is a web running fore and aft on the hull's centreline, from the transverse web that supports the forward end of the mast step, to around the half height bulkhead that supports the aft end of the forward berth. I think the plate the rod is attached to is glassed into the top of that web so you won't have to glass to the hull to make the repair, just to the web (I think), which should be easier to do. Have a look at the 'Spider design' drawing at: https://drive.google.com/file/d/0B7X4Y5iVFYAKcDd4ZlhWNGZzdmM/view I think the lower end of the rod is shown as a short little line, rising from that fore and aft centreline web. https://c-c-37-40.blogspot.com/p/blog-page.html Another drawing that my be helpful: https://drive.google.com/file/d/0B7X4Y5iVFYAKYTJxRDJBc3BvLWM/view If we're lucky, Rob Ball may remember this detail, and may be able to let us know if I am correct in my guess (or not).
